Abstract

Minor uncommon FA from Hesperopeuce mertensiana (a gymnosperm species of the Pinaceae family) seed oil were characterized through a combination of silver ion TLC of their FAME, and GLC coupled with MS of their picolinyl derivatives. These uncommon components have the structures 16-methyloctadecanoic (anteiso-19:0), 16-methyl-cis-9-octadecenoic (anteiso-19:1), and 1 6-methyl-cis-9,cis-12-octadecadienoic (anteiso-19:2) acids. These branched C19 acids were identified earlier in the wood of Picea abies, which would indicate that such acids could be widespread, though minor, components of Pinaceae lipids.
